Description

Verfahren zur Stabilisierung von Polymerisaten und Mischpolymerisaten des asymmetrischen Dichloräthylens Polymerisate und Mischpolymerisate des asymmetrischen Dichloräthylens neigen beim Erhitzen zur Abspaltung von Chlorwasserstoff. Damit verbunden ist eine starke Verfärbung. Beim Verarbeiten auf der `Falze beginnen die Produkte gleichzeitig zu kleben. Durch diese Instabilität wird die Verarbeitung derartiger Produkte sehr erschwert und ihre Verwendbarkeit für viele Zwecke eingeschränkt.Process for stabilizing polymers and copolymers of asymmetric dichloroethylene polymers and copolymers of asymmetric Dichlorethylene tend to split off hydrogen chloride when heated. In order to there is a strong discoloration associated with it. When processing on the `folds, the Gluing products at the same time. This instability makes processing Such products are very difficult and their usability is restricted for many purposes.

Es wurde nun gefunden, daß Polymerisate und Mischpolymerisate des asymmetrischen Dichloräthylens, die geringe Mengen von Derivaten des Äthylenimins enthalten, bei denen das Wasserstoffatom der Imingruppe durch den Rest einer organischen Säure, z. B. der Kohlensäure, einer Carbonsäure oder Sulfosäure ersetzt ist, eine erhebliche verbesserte Stabilität besitzen. Derartige Derivate des Äthylenimins sind z. B. N-p-Toluolsulfoäthylenimin, N-phenyl-N'-N'-äthylenharnstoff, N-N'-Äthylen-äthylurethan und Butandiol-di-kohlensäureester-bis-äthylenimid.It has now been found that polymers and copolymers of the asymmetric dichloroethylene, the small amounts of derivatives of ethyleneimine in which the hydrogen atom of the imine group is replaced by the remainder of an organic Acid, e.g. B. the carbonic acid, a carboxylic acid or sulfonic acid is replaced, a have significantly improved stability. Such derivatives of ethyleneimine are z. B. N-p-Toluenesulfoäthylenimin, N-phenyl-N'-N'-ethylene urea, N-N'-ethylene-ethyl urethane and butanediol-di-carbonic acid ester-bis-ethyleneimide.

Je nach Anforderungen und je nach Art der Verarbeitung können leichter oder schwerer flüchtige Derivate des Äthylenimins verwendet werden. Handelt es sich z. B. darum, die Lösung der Polymerisate bzw. Mischpolymerisate zu stabilisieren, so kann häufig ein relativ flüchtiges Äthyleniminderivat verwendet werden. Erfolgt die Verarbeitung z. B. durch Walzen und Pressen bei hoher Temperatur, so ist es zweckmäßig, ein schwerer flüchtiges Derivat des Äthyienimins zu verwenden. Natürlich können auch Gemische von höher= xnd "tiefersiedenden Äthyleniminderivaten verwendet werden. .Depending on the requirements and the type of processing can be easier or less volatile derivatives of ethylene imine can be used. Is it z. B. about stabilizing the solution of the polymers or copolymers, a relatively volatile ethyleneimine derivative can often be used. He follows processing z. B. by rolling and pressing at high temperature, so it is expedient, a less volatile derivative of Ethyienimines too use. Of course, mixtures of higher boiling ethylene imine derivatives can also be used be used. .

Die Menge des benötigten Stabilisators ist abhängig von der Art des zu stabiTisie@enderi: Hochpolymeren und von den an die Stabilität gestellten Anforderungen. lm allgemeinen kommt man mit o, i bis 5 °/o Äthyleniminderivat aus. Da die Derivate des Äthylenimins in den Hochpolymeren im allgemeinen löslich sind, erhält man mit ihnen Massen von besonderer Klarheit. Beispiel r Ein Mischpolymerisat aus 84 Teilen asymmetrischem Dichloräthylen, i¢ Teilen Vinylchlorid und 2 :Teilen Acrylnitril vom, k-Wert 58 wird bei 15o° 5 Minuten gewalzt, dann zu einer Folie ausgezogen und bei i5o° gelagert. Der gleiche Ansatz wird unter Zusatz von 10/0 N-Phenyl-N'-N'-äthylenharnstoff bzw: i °/o p-Toluolsulfoäthylenimin ausgeführt. Die dabei .erhaltene Folie zeigt folgendes Aussehen: Min. Walzen , - Wärmelagerung: Zusatz bei i$o° 1 / ,, Std. I. 1/2 Std. l x Std. I 2 Std. ( q Std. - dunkel-` schwärz schwarz schwarz schwarz schwarz braun stark _ stark stark . stark stark ' blasig blasig blasig blasig blasig i °/o p-Toluolsulfoäthylenimin , helI= - braun dunkel- dunkel- dunkel- schwarz braun braun braun braun stark blasig i °/o N-Phenyl-N'-N'-äthy- ..hell- braun braun braun braun schwarz lenharnstoff bräun stark blasig Die Verfärbung und Blasenbildung wird also durch Zusatz der Äthyleniminderivate stark verzögert.The amount of stabilizer required depends on the type of high polymer to be stabiTisie @ enderi: and the requirements placed on stability. In general, 0.1 to 5% ethyleneimine derivative is sufficient. Since the derivatives of ethyleneimine are generally soluble in the high polymers, they are used to obtain compositions of particular clarity. Example r A copolymer of 84 parts of asymmetric dichloroethylene, 1 parts of vinyl chloride and 2 parts of acrylonitrile with a k value of 58 is rolled at 150 ° for 5 minutes, then drawn out into a film and stored at 150 °. The same approach is carried out with the addition of 10/0 N-phenyl-N'-N'-ethyleneurea or: i% p-toluenesulfoethyleneimine. The resulting film looks like this: Min. Rolling, - heat storage: Addition to i $ o ° 1 / ,, hrs. I. 1/2 hrs. Lx hrs. I 2 hrs. (Q hrs. - dark-`black black black black black brown strong _ strong strong. strong strong 'blistering blistering blistering blistering i ° / o p-toluenesulfoethyleneimine, helI = - brown, dark, dark, dark, black brown brown brown brown strong blistered i ° / o N-phenyl-N'-N'-ethy- .. light brown brown brown brown black Lenurea browns strongly blistered The discoloration and blistering is thus greatly delayed by adding the ethylene imine derivatives.

Beispiel e Eine 25%ige Lösung eines Mischpolymerisates, bestehend aus- gleichen Teilen asymmetrischem Dichloräthylen und Vinylchlorid in Cyclohexanon, wird mit i °/o p-Toluol-sulfoäthylenimin versetzt. Bei elfstündigem Erhitzen auf i2o° -bleibt die Lösung vollkommen klar und färbt sich nur noch sehwach braun, während eine entsprechende unstabilisierte Lösung vollkommen trüb wird und sich stark verfärbt.Example e A 25% solution of a copolymer, consisting of equal parts of asymmetric dichloroethylene and vinyl chloride in cyclohexanone, i% p-toluene-sulfoethyleneimine is added. When heated for eleven hours i2o ° - the solution remains completely clear and only turns a weak brown color, while a corresponding unstabilized solution becomes completely cloudy and strongly discolored.
